Air Fryers Might Pose Health Risks When Used Too Much vs. Traditional Ovens

A 28-year-old woman thought her air fryer was the “healthier choice,” until the smell of burnt grease started creeping into everything she cooked. The chips still came out crispy, but the basket never felt truly clean, no matter how fast she wiped it after each use.

Then the cleaning rabbit hole hit. She tried the easy stuff people swear by, like tossing trays in the dishwasher, soaking parts in warm water with a dishwasher tablet, and even seeing videos that suggest lining the fryer with foil or running it empty with soap. The problem is, this machine is picky, the non-stick coating can get wrecked, and the central unit cannot be submerged without risking a costly replacement.

So the real twist is, the way you clean your air fryer can decide whether it stays a kitchen win or turns into a PFAS-and-stink problem.

After each use, give your air fryer a quick wipe-down.

Dr. Anderson suggests rolling up your sleeves and doing a more thorough job regarding the deeper clean.

“For a monthly deep clean, you’ll need to clean all the accessories and inside the appliance more thoroughly to remove burnt-on food, grease, and odours,” he explained.

One of his go-to tips is surprisingly simple: fill the basket or drawer with warm water, drop in a dishwasher tablet, and leave it overnight to soak. Rinse the next day, and you’ll be amazed at how easily the grime lifts away.

She started with a quick wipe-down after every batch, then wondered why the “monthly deep clean” advice kept sounding like a warning.

But here's where people often make mistakes: throwing the tray in the dishwasher might seem convenient, but it can do more harm than good. The dishwasher can damage the non-stick coating many air fryers rely on.

Once that coating’s gone, cleaning becomes harder, and food is more likely to stick, burn, and generally taste worse.

Another important rule is never to submerge the air fryer's central unit in water. The heating element is not waterproof; soaking can ruin the appliance, potentially leading to a pricey replacement.

When she followed the warm water plus dishwasher tablet soak overnight, she felt smug, until she realized she might be doing it wrong for the parts that matter.

Health Considerations with Air Fryers

A deeper clean is applied based on how frequently you use your model.

While cleaning hacks on TikTok and Instagram may look impressive, don’t be too quick to try them. Some of these so-called shortcuts can be dangerous, especially those that involve lining the air fryer with foil or running it empty with soap inside.

“Unless you want an unexpected visit from the fire brigade, it’s best to stick to the basics,” said Anderson.

So why bother with all this? Besides avoiding the smell of reheated fish on your next batch of chips, regular cleaning also matters for your health. If your air fryer has a non-stick surface, it may contain PFAS (polyfluoroalkyl substances), the same group of chemicals used in many non-stick pans.

These so-called “forever chemicals” have been linked to health risks, but the issue mainly arises when the coating gets damaged.

The moment she tossed the tray in the dishwasher, she noticed the non-stick surface looking different, like it was already paying the price.

That’s another reason not to go at your air fryer with steel wool or throw it in the dishwasher. Damaging the lining could release tiny particles you don’t want in your dinner.

In short, taking a few minutes to wipe down your air fryer now can save you from sour flavours, potential health risks, and even an early appliance breakdown. Ensure your trusty air fryer does its job without making your kitchen smell like last Tuesday's burnt bacon.

After she skipped the “never submerge the central unit” rule while trying to get rid of burnt-on odours, the whole thing stopped feeling like a shortcut and started feeling like a gamble.

The rise in popularity of air fryers highlights the need for mindful cooking practices.

Her air fryer didn’t get “too risky” overnight, it got risky the second the coating and heating unit took the wrong kind of cleaning.
